TL;DR: In this paper, the surface topography of Be, Al, V, SS, Inconel, Cu, and Nb under high fluence helium irradiation is reviewed and correlated with the relative width, WR = FWHM/Rp, of the implantation profile.

TL;DR: In this paper, the surface blistering of niobium by implantation with helium ions in the 9 to 15 keV range was investigated and the apparent disappearance of blisters at sufficiently high doses was believed to be an equilibrium effect.

TL;DR: This study test the hypotheses that digital infrared thermographic imaging will reveal a correlation between load application to the skin and the creation of blisters, and a correlations between thermographic readings and contact thermometric temperatures.
Abstract: Background/Purpose: Friction blisters on the foot are a debilitating pathology that have an impact on activities of daily living and can severely impair function. The purpose of this study was to test the hypotheses that digital infrared thermographic imaging will reveal: 1) a correlation between load application to the skin and the creation of blisters, and 2) a correlation between thermographic readings and contact thermometric temperatures. Methods: Apparatus was developed to cause the formation of heel blisters through controlled load application (70 kPa). One foot of each of the 30 healthy volunteers (21 men and 9 women), with an age range of 31 ± 8 years, was subjected to load until a blister formed, after which load application ceased and temperature measurements were taken at set times during the following 5.5 h. Temperature measurements were also taken using a contact thermometer. Results: The majority of the participants (77%) blistered within 18 min of load application. All the blisters created showed significant increases in local temperature compared to baseline during blister creation (P 8). Conclusion: These results suggest that thermographic images may prove useful for the remote assessment of traumatically damaged foot skin.

TL;DR: In this article, the authors evaluated hydrogen-induced damage including blister and cracking in friction stir welded low carbon steel and found that after hydrogen charging for 2 hours, irreversible dome-shaped blisters and internal cracking began to appear on the surface of the base metal, while the blisters or cracking were hardly observed in the stir zone.

TL;DR: High enzyme activities were found in spontaneous blisters, and suction blister fluids obtained from developing lesions showed increased levels of gelatinase and elastase‐like enzymes, which could be either enzyme‐inhibitor complexes or aggregates.
Abstract: SUMMARY
Proteolytic enzymes may be involved in blister formation in dermatitis herpetiformis (DH). We have examined collagenase, gelatinase and elastase-like enzyme activities in fluids collected from spontaneous blisters and from suction blisters raised on developing DH-lesions induced by application of potassium iodide. Control suction blisters were raised on unaffected DH-skin and on healthy volunteers. High enzyme activities were found in spontaneous blisters, and suction blister fluids obtained from developing lesions showed increased levels of gelatinase and elastase-like enzymes. Inhibitor studies revealed that a part of the elastase-like enzyme activity might be derived from inflammatory cells. Gel filtration chromatography disclosed two separate elastase-like enzymes which, as they had high molecular weights, could be either enzyme-inhibitor complexes or aggregates.
